sorry guys but i read alot aboaut CAI and how it doesnt do much, as in HP gains, except it makes it sound abit louder and much nicer. But i also heard it wastes alot of gas.....some say they dont see anything with regards to gas mileage....so about now im totally confused !! i drive a 2003 auto civic si (ex in the states) and if i put a CAI on is it gonna kill my gas or make it better??
some saying more air=more gas...and others are disagreeing...can somebody help me this ??

Agian im sorry if im asking the same question again.....i apologize and it will greatly appreciated if u guys coulod help me out

Basically gas mileage gets decreased b/c when you install it, you cant help but mash on the gas to hear that awesome intake sound. People just tend to drive a little harsher when they install a cai ot sri. I have a sri and if I drive normally I still get my 32-33mpg.

so if i keep driving normally with the CAI on it WONT waste more gas ??

it def doesn't do much in the hp gains (2-5 hp im guessing). and as far as the gas mileage i didnt notice n e difference in mine and i keep track of it. more air doesn't mean that ur car is going to compensate for it (sending more fuel).


i think all these guys having gas probs is the fact there beating there car more often (trying to hear the intake) and runnin to redline more often. hence the more gas usage.

if u wanna hear the intake take off the silencer box on the intake (big black box closest to the battery). now u have a intake sound, as much hp gains as the cold air or close (cuz we all know its a joke), ur safe cuz the filter is in the box directly on top of the throttle body, and it didn't cost u a dime.

so a CAI is basically useless then....then why are ppl buying it and putting in there engine...... wouldnt be a waste of money ??? i thought it helped to get air into the car easier...but if it doesnt do much why get it other than for looks ?? cuz im not gonna be driving around with my hood up showing pple what i got (or dont got) in my engine

It has been determined that adding a cai or sri that more air isnt added. Air is just added easier. Think about it the engine can only handle so much air at once. Its a confined area where would the extra air go? Perhaps maybe if you bored the head out this might be possible, but no adding a cai or sri doesnt add more air, and therefore more fuel isnt added to compensate.

yea thats makes more sense...i feel dumb lol....so would u guys recommend getting a CAI...cuz this would be my first mod on my car in the engine....

 
Rep Power: 303

I wouldnt say it was useless...I have a sri and I do notice some gains in the high end, but def lost some low end. Plus it sounds pretty cool. If you really think its a waste just get the sri, its about half the price and does the same thing.

oic thanx....well i know a guy that is selling a CAI for pretty cheap...so i was just wondering if i should get it or not ???

 
Rep Power: 303

Ok if you have an auto then chances are it wont fit. Most cai are made for manual transmission, I've only seen injen make a cai for an auto. So if his is made by aem chances are it wont fit.

 
Rep Power: 302

Can't hurt if you get one. Especially if you can get it for cheap.. adds a nice sound to your car

 
Rep Power: 288

not worth it unless like u said ur showing off ur motor all the time...

u wanna b fast save ur money and get a turbo thats the only intake system that works.

 
Rep Power: 303

Doh nvm you have an si they are all manual heh. Is the cai you are getting coming from an si?

 
Rep Power: 0

yea its a injen one...it looks pretty nice.....so u guys would recommend it if i get the injen CAI if i can get it for an ok price ??

 
Rep Power: 303

Yeah as long as his car is an si as well. I'd say go for it, what exactly is he charging you. Also make sure it is a cai. The cai will wrap down by the transmission down near the front bumber. If the filter is visible in plain sight then its just a short ram intake and hes trying to screw you.

no its an automatic =...( yea i regret it. its an si in canada...i think their the same as an ex in the US

 
Rep Power: 0

yea it's a CAI...lol that i know hehhe so it'll be good ?? it wont effect my car in any way would it ??

 
Rep Power: 303

oh oh oh. Uhm if his is a manual then I think you are sol (**** outta luck) The si in the US is way dif then the ex.

 
Rep Power: 0

oic...damn....i dunno so if i drive a si and the other guy is driving lets say lx or ex in canada...it wont fit ??

 
Rep Power: 303

http://automobiles.honda.com/models/...rDetected=True Thats what the SI in the US looks like. Is this what you have?

 
Rep Power: 338

Rep Power: 0

nope...its nutting like that one in canada, that one is the SiR lol

 
Rep Power: 303

omg lol. OK if he has an ex or an lx thats an auto as well it should fit no problem. If he has a manual I think you are screwed.

 
Rep Power: 0

yea...he said he had a automatic too......but if he does have a lx or ex (in canada which has 115 HP) while my si has 127hp would it still fit ??

 
Rep Power: 303

yeah it should.
